Vestibulocochlear or VIII cranial nerve
The Vestibulocochlear nerve has two components, with the cochlear provides innervation to the hearing apparatus while the vestibular branch is concerned with balance. Conduction deafness results from interference with the transmission of sound waves in the external canal or middle ear to the organ of Corti. In sensorineural hearing loss, the lesion can be in the inner ear, the vestibulocochlear nerve or the brain. Because of the extensive bilateral connections of the ear, unilateral sensorineural hearing loss is usually due to lesion of the nerve nucleus or the nerve itself. Bilateral hearing loss can be either due to a central lesion or bilateral exposure to toxins and infectious agents.
• Auditory Component
- Look
o See if the child is wearing a hearing aid and remove it, while testing for hearing impairment.
o Examine the pinna and look for scars behind the ears.
o Do an otoscopic examination of both ears. Look for wax or other obstruction in the external auditory meatus and perforation of the tympanic membrane.
- Whisper test
The Whisper Test is a screening test for hearing loss in older children and correlates with a hearing loss of 30 decibels.
o Stand about two feet behind the child on one side so that they cannot read your lips.
o Place your finger on the external auditory meatus of the ear which is not being tested to mask the sound.
o At the end of your exhalation, whisper a word with two distinct syllables towards the ear which is being tested.
o Ask the child to repeat the two syllable word.
o Repeat the test on the other side

Hypoglossal or XII cranial nerve
The Hypoglossal nerve provides motor supply to the intrinsic muscles of the tongue.
• Look
- Ask the child to open the mouth and inspect the tongue on the floor of the mouth. Observe the tongue for signs of wasting or fasciculations.
- Next, ask the child to protrude their tongue 'Stick out your tongue'. Look for deviation of the tongue from midline. In peripheral hypoglossal lesion, there will be atrophy and fasciculations and the tongue will deviate towards the side of the lesion. In central lesion, there is spastic paralysis of the tongue without atrophy or muscle fibrillation and paralysis and the tongue deviates to the opposite side.
• Motor Component
- Ask the child to push the tongue into each cheek while you press from outside with your finger.
2. A hearing test that can determine this illness only if you suffer from hearing loss.
Nonspeech signs associated with hypokinetic dysarthria may include characteristics dealing with the face, eyes, hands, arms, and trunk. The individual may have an expressionless look to their face as well as weakness with gestures in the hands, arms, and face that would normally match the person’s prosody when speaking. Overall, their social interaction with others can be emotionless. Eye blinking occurs less frequently than normal and their head gaze does not match where their eyes are looking. These patients swallow infrequently which leads to drooling. A tremor may be present in the jaw, lips, and tongue as well as limited movement during speech even though strength of these structures is often normal.
Tongue tie is when your child’s tongue is not able to move freely in his or her mouth. A band of tissue called the frenulum runs from the underside of the tongue to the bottom of the mouth. This band should be thin enough and long enough to allow the tongue to move freely in all directions. When this band is too thick or too short, it can prevent the tongue from moving normally.

Specific Purpose: To help people to understand what Audism is and that the lack of an ability to hear does not mean they are incapable of performing tasks.
.... To do this you may use a sticker chart, give the child some candy, or buy the child something they want. Be sure not to go nuts. Doing this will make the child react to praise the same way they act to punishment. Praise and the reward the child, but don't over exaggerate and scare the child.
Her phonetic inventory is well developed. She has no troubles creating the age-appropriate speech sounds. The child is just above normal because she can produce more adult-like sounds than her peers. She has control over her articulators and she knows how to manipulate her oral cavity to produce the correct sounds.
Hearing loss can affect a child dramatically in their early development. It is important to be aware and cautious of noticing signs towards possible hearing loss, because language and communication skills deve...

Hearing loss is a major global public health issue. Hearnet (2017) defines hearing loss as “a disability that occurs when one or more parts of the ear and/or the parts of the brain that make up the hearing pathway do not function normally” (para. 1). There are many different types of hearing loss, which can have multiple causes, giving each individual experiencing the issue a unique hearing loss case. These types include Auditory Processing Disorders, when the brain has problems processing sound information; Conductive Hearing Loss, a problem with the outer or middle ear which prevents sound making its way to the inner ear; and Sensorineural Hearing Loss, when the Cochlea or auditory nerve is damaged and cannot
Vestibular System Athletes must accomplish amazing feats of balance and coordination of the body. As scientist, Mikhail Tsaytin discovered in the 1970s, acrobats can successfully make a two person human tower in the dark, but after adding a third acrobat, not even the most talented can maintain the balance required to keep the tower intact while in the dark (1). What does darkness have to do with it? The point is that balance relies on at least three signals coming from the body, and one of those is sight. Once you eliminate one of these signals, the body cannot accomplish the required task.
This is called newborn screening. Within newborn screening there three test normally given. This screening occurs not long after birth and can provide details about developmental, genetic and metabolic disorders. Two test completed in the screening are for hearing loss and for critical congenital heart disease (CCHD). The hearing test is completed by placing either a tiny earpiece of microphone in the infants’ ear with a sound playing to see whether the infant responds or not. Another way the test is given is by using tiny earphones and electrodes that are placed on the infant’s head to detect the brains response to sound (National Institute of Child Health and Human Development, 2015). The other tests that may be performed is the CCHD screen which the amount of oxygen in an infant’s blood is measured. In order to do this a sensor is placed on the infants’ skin for a couple of minutes, while the sensor measures the level of oxygen in the blood. Within in newborn screening there is also another tests which is the most important
